Schools go for the government $$$$$$$$$$ and care less about the facts of life.
Most people like/love chocolet. As a toddler you paint their thumb with a hot pepper formula and soon they discover the thumb is not good, wonder if the chocolet was painted with a little cayenne soon the brain would forget about it? I have seen people so addicted to chocolet you would think it was as bad as drug addicts, maybe the scientist have such addicting drugs in cheap chocolet?
